Zovala za singano zimakhala ndi ma cylindrical roller bearings.Poyerekeza ndi mainchesi awo, zodzigudubuza ndi zoonda komanso zazitali.Wodzigudubuza uyu amatchedwa singano.Ngakhale ili ndi gawo laling'ono la mtanda, kunyamula kumakhalabe ndi mphamvu yonyamula katundu wambiri, choncho kumakhala koyenera makamaka pazochitika zomwe zimakhala ndi malo ochepa ozungulira.

Malo ozungulira a singano odzigudubuza amamangika pang'ono kumapeto kwa proximal kumapeto.Zotsatira zowongolera zolumikizirana ndi singano zitha kupewa kuwononga kupsinjika m'mphepete.Kuphatikiza pa kabukhuli, mayendedwe omwe angagwiritsidwe ntchito popanga uinjiniya wamba, monga: mayendedwe otseguka okoka singano (1), zotsekera zotsekera za singano (2), zodzigudubuza za singano zokhala ndi mphete zamkati (3) komanso zopanda Kuphatikiza pa mkati mwa mphete za singano zodzigudubuza (4), SKF imathanso kupereka mitundu yosiyanasiyana ya singano zodzigudubuza, kuphatikizapo: 1, mipingo ya singano ya singano 2, mayendedwe a singano opanda nthiti 3, zitsulo zodzikongoletsera za singano 4, kuphatikiza singano / mpira 5, kuphatikiza singano / kuponya mpira 6, kuphatikiza singano / cylindrical wodzigudubuza kukankha mayendedwe.

Zokokedwa chikho singano wodzigudubuza mayendedwe

Zokoka kapu zodzigudubuza zokhala ndi singano zokhala ndi mphete yopyapyala yakunja.Mbali yake yayikulu ndi kutalika kwa gawo lotsika komanso kuchuluka kwa katundu.Amagwiritsidwa ntchito makamaka popanga masinthidwe okhala ndi mawonekedwe ophatikizika, mtengo wotsika mtengo, ndipo dzenje lamkati la bokosi lonyamulira silingagwiritsidwe ntchito ngati njira yolumikizirana ndi khola la singano.Ma bearings ndi nyumba zonyamula ziyenera kuyikidwa muzosokoneza.Ngati axial positioning imagwira ntchito monga mapewa a bokosi ndi mphete zosungira zingathe kuchotsedwa, ndiye kuti bore mu bokosi lonyamulira likhoza kukhala losavuta komanso lopanda ndalama.

Zovala za singano zokokedwa kumapeto kwa shaft zimatseguka mbali zonse (1) ndikutsekeka mbali imodzi (2).Nkhope yoyambira kumapeto kwa mphete yotsekedwa yotsekedwa imatha kupirira mphamvu zazing'ono za axial.

Zovala za singano zokoka kapu nthawi zambiri sizikhala ndi mphete yamkati.Kumene magazini sangathe kuumitsidwa ndi kupukuta, mphete yamkati yomwe ili patebulo ingagwiritsidwe ntchito.Mphete yakunja yachitsulo yolimba ya chikhomo cha singano chokokera singano sichingasiyanitsidwe ndi msonkhano wa khola la singano.Malo aulere osungira mafuta amatha kuwonjezera nthawi yobwezeretsanso.Ma bearings nthawi zambiri amapangidwa mumzere umodzi.Kupatula mndandanda waukulu wa 1522, 1622, 2030, 2538 ndi 3038, ali ndi misonkhano iwiri ya singano ya singano.Mphete yakunja yonyamula ili ndi bowo lamafuta.Malinga ndi zosowa za ogwiritsa ntchito, masikelo onse okhala ndi mizere imodzi yokhala ndi shaft yayikulu kuposa kapena yofanana ndi 7mm amatha kukhala ndi mphete zakunja (code suffix AS1) yokhala ndi mabowo opaka mafuta.

Zokoka kapu singano wodzigudubuza mayendedwe ndi mafuta chisindikizo

Kumene zosindikizira zamafuta sizingayikidwe chifukwa cha kuchepa kwa danga, zotchingira za singano (3 mpaka 5) zokhala ndi chidindo chamafuta zodinda mphete zakunja zitha kuperekedwa zotsegula kapena zotsekeka.Mtundu woterewu uli ndi chisindikizo chamafuta akukangana cha polyurethane kapena mphira wopangira, womwe umadzazidwa ndi mafuta a lithiamu okhala ndi ntchito yabwino yolimbana ndi dzimbiri, yoyenera kutentha kwa -20 mpaka + 100 ° C.

Mphete yamkati yamtundu wotsekedwa ndi mafuta ndi 1mm yokulirapo kuposa mphete yakunja.Izi zimathandiza kunyamula kuonetsetsa kuti chisindikizo cha mafuta chimagwira ntchito bwino pamene shaft ili ndi kachidutswa kakang'ono kokhudzana ndi bokosi lonyamulira, kuti kuberako kusaipitsidwa.Mphete yamkati yonyamula imakhalanso ndi mabowo opaka mafuta, omwe amatha kubwezeretsedwanso ndi mphete yakunja kapena mphete yamkati molingana ndi zosowa za kasinthidwe konyamula.
